Title: Vehicular hydraulic braking system with wheel-slip control - safeguards rear-wheel braking in antislip mode by provision of fluid from auxiliary displacement cylinder
Inventor: ZAVISKA DALIBOR
IPC: B60T8/42
Filed: 1992-03-19
Abstract: The fluid displacement element (3) in parallel with the inlet wave (1) of the rear-wheel brake cylinder (HA) is pressurised in normal operation so that the build-up of braking pressure depends upon its displacement. A wheel-slip detector (17) is wired to the electronic controller (5) which operates the inlet and outlet valves (1,6) as required. If e.g. the auxiliary pressure pump (16) fails or an electrical fault leaves the inlet valve closed, a vol. of fluid dependent on the dia. and stroke of the displacement element is supplied to the brake cylinder. ADVANTAGE - Reliable system that prevents total failure of rear-wheel braking in event of electrical or electronic disturbances.

Patent DE-4217924-A1 (DE)
IPC: F16C11/04
Filed: 1992-05-30
Abstract: The joint comprises one part with a bearing bore (12), a friction torque sleeve (13) accommodated in the latter, and a second part designed as a link and having an articulation spindle (16) which is designed as a polygonal profile and is accommodated non-rotatably in a matching longitudinal recess (14) in the friction torque sleeve (13). The friction torque sleeve (13) is of intrinsically elliptical cross-section, the regions corresponding to the end caps (20, 20') being oversized relative to the cylindrical bearing bore. During press-fitting into the bearing bore (12), the friction torque sleeve (13) is elastically deformed and is thereby pressed into frictional engagement by its end caps (20, 20') with the bearing bore. The polygonal profile of the articulation spindle (16) is accommodated with a predetermined play in the longitudinal recess of the friction torque sleeve (13), with the result that the spindle (16) can pivot virtually without resistance within the pivoting range predetermined by the said play, while, if rotated further, the friction torque sleeve (13) is rotated along with it, counter to the set friction torque. <IMAGE>
